摘要：The use of the isolated hybrid power systems is being popular due to the continuous increasing gap between demand and supply of conventional energy sources and intermittent nature of non-conventional energy sources. Normally, the non-conventional energy source such as wind have induction generator to generate electricity but induction generators require reactive power for its operation and this demand is continuously changing by the variation of load and wind power. The synchronous generator used in hybrid system for generating power through diesel system is supplying reactive power to the system partially; therefore, another source of reactive power is required to fulfill this demand. In this paper, the static VAR compensator (SVC) and static synchronous compensator (STATCOM) using a proportional-integral controller (PI) are used as reactive power compensator. The dynamic performance of SVC and STATCOM are investigated for wind-diesel and wind-diesel- microhydro power systems ate constant slip operation of induction generators. The results show that the STATCOM is a better option than that of SVC for reactive power control of the hybrid system.
